Book excerpt: Land loss restoration along the southeast Louisiana coast relies on the replenishment of sand from the sediment of the Mississippi River. To further the understanding of sediment transport and hydraulic characteristics of the lowermost segment of the river, the Louisiana Coastal Protection and Restoration Authority (CPRA) funded construction of the Lower Mississippi River Physical Model (LMRPM). This distorted-scale, movable bed model encompasses the lowermost 193-mile reach of the river, including from Donaldsonville, Louisiana to the Gulf of Mexico the Bonnet Carre Spillway and planned river sediment diversions. Designed to replicate the prototypical river hydraulics and bulk bedload (sand) transport, scaled historic river discharges are routed through the model.. Lightweight synthetic particles representing the very fine to fine grain sand sediments of the lower river are injected based on the results of a numerical sediment transport simulation from Tarbert Landing to the Gulf of Mexico. The depths and opaqueness of the model make it challenging to non-destructively measure real-time sediment transport. The objective of the research is employ non-destructive methods to measure reach-by-reach sediment levels that can be used to predict the scour and deposition of the bed load sediments. Having a method to locate and quantity sediment accumulations would benefit both navigational and coastal restoration stakeholders. During a LMRPM test of 1995 through 1999 discharges, ultrasonic sensors measured the sediment bed levels along a 17-mile reach of the model. Measured year-to-year bed elevation changes were translated into volumetric changes and compared to computed bed volume changes using boundary shear stress results from 1-D, unsteady flow numerical simulations. The measured-to-observed data, plotted in a scatter graph, align closely to 1:1 regression line of observed-to-observed values validating the process. This approach was also shown to successfully predict deposition patterns in one of the prototype lowermost river crossings.

This book was released on 1981 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: To test the applicability of various one-dimensional sediment-transport numerical models of movable-bed channels to Pool 20 to the Mississippi River, detailed field data were first collected, and several numerical models were subsequently evaluated using these field data. Chapter I describes the detailed results from a sediment sampling field study conducted in 1978 near Buzzard Island (RM 347-55) in Pool 20 of the Mississippi River. Variations in the longitudinal and transverse distributions are presented for various flow quantities and sediment characteristics, and are analyzed in connection with the prevalent shoaling problem in the Buzzard Island study reach. Chapter II evaluates the performance of four mathematical simulation models which used the data from a complimentary field study conducted in 1976 to establish the initial conditions when predicting the 1978 conditions. The four models evaluated were: (1) the HEC-6 model provided by the Hydrologic Engineering Center, U.S. Army Corps of Engineers; (2) the SUSR; (3) UUWSR models employed at the Colorado State University; and (4) the CHAR2 model used by the Sogreah consulting firm in Grenoble, France.

Book Synopsis A Mathematical Study of the Impact on Salinity Intrusion of Deepening the Lower Mississippi River Navigation Channel by : Billy H. Johnson

This book was released on 1987 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US Army Engineer District, New Orleans has been evaluating the feasibility of deeper draft access to the ports of New Orleans and Baton Rouge, Louisiana. One of the factors being considered in the evaluation is the impact of the deeper channel on salinity intrusion in the Lower Mississippi River. The importance of such an evaluation is because the city of New Orleans relies primarily upon the Mississippi River for its supply of fresh water. A major reason for conducting the numerical modeling study was not only to evaluate the impact of a deeper channel on salinity intrusion using historical riverflows but also to use the numerical model to determine the impact on the wedge intrusion of increasing the height of natural river crossings, i.e., creating a sill in the river. To address the question of the stability of such a sill composed of natural sediment, the HEC-6 computer program Scour and Deposition in Rivers and Reservoirs, HEC (1977), was applied.

Book Synopsis Suspended Sediment and Bed Material Studies on the Lower Mississippi River by : Lamont G. Robbins
Download or read book Suspended Sediment and Bed Material Studies on the Lower Mississippi River written by Lamont G. Robbins and published by . This book was released on 1977 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate purpose of sediment studies is to develop a workable knowledge of the basic principles controlling the transport of sediment in the Lower Mississippi River and to apply this knowledge toward effective and economical stabilization works for flood control and navigation. The more immediate purpose of this report, however, is to present the data that have been collected and analyzed to date (1929-1974) and to show what trends exist in the quantities and sizes of suspended and bed sediments for the Vicksburg District.
